/**
* This class/test was originally written for WTP bug 106158, and adapted to a
* generic "platform" test case, since some of the problem was due to bug
* 107121
*
* Thanks for Jeffrey Liu (jeffliu@ca.ibm.com) who wrote the test for WTP.
*
* And, thanks to Eric Glass <ericglass@maximus.com> for opening bug 106158
* (100% CPU for over 3 minutes opening a directory in the Navigator view with
* over 2000 HTML files) https://bugs.eclipse.org/bugs/show_bug.cgi?id=106158
* and for providing 2500 "generic" HTML files for the original test case in
* WTP.
*
* modified by David Williams for platform level test that does not depend on
* WTP or, for that matter, any meaningful content type. The content type
* assumed there is designed simply to "take a while" to complete, if asked
* for its properties.
*
* Note, since this test companion "ContentDescriberForTestsOnly", simply uses
* "sleep" to simulate computations, it only effects Elapsed Time (not CPU
* Time).
